Appiiiia'cion ala January 27, 1912. seriai'No. 673,9511" To all whom 'it may concern: y Be it known that I,- IZAAK FRENKIL, a citizen of the` United States, and resident of Baltimore, Maryland, have invented certain Improvements in Non-Freezing Water- Closets, of which the following is a specilication.- 'Y

In the description of the said invention which follows, reference ismade tothe accompanying drawings forming a part hereof, and in which:- l i Figure 1 is-- an exterior side'view of the improved closet; and Fig. `2 an enlarged Vertical side section of the valve mechanism and their attachments lemployed therein.

Fig. l3 .is a plan of Fig.' 2; and Fig. 4a section taken, on the line -aa in Fig. 3.

Fig. 5. is a section taken 4on the line y-y in Fig. 2; and Fig. 6 is a perspective view of' a certain valve forming a part ofthe apr paratus. Referring now to the drawing -1 is vthe bowl of the closet, andA 2 a. .shellv secured by a nipple .to the nozzle 3 of t-he bowl. ,l

4 is a pipe leading from the shell 2 to the `flushing tank 5 whichis shown only in Fig.

l. rlhis tank is'itted with a valve to admit air as the tank is discharged of walter.

6 is the main water supply'pipe extending downward from the shell 2, to the valve chamber 7 the bottom of whichv is connected to the service pipe 9; The said valve chamber is provided with a nozzle 10 to be used in case it should/be necessary to connect' the service pipe to the side of the shell instead of to its bottom vas shown.

12 is a drain pipe leading from the valve chamber -7 to the trap 13 shown only in Fig. 1.

14 is a valve comprising the central part a which is cylindrical and [its closely'to the bored portion b of the chamber 7, so as to lcontrol the drain pipe 12; and the softrubber lower en d c of the valve is adapted to close the opening d when the drain pipe 12 is open to the trap 13. The portion e vof the valve 14 between the cylindrical part4 a and the soft rubber end c, is tapered,

asis also the portion `fabove, to which is screwed the valve stein 15 extendin ward and through the packing box 17 in the top of the shell 2. In order that waiter may pass` the valve 14 when lifted, and` enter the shell 2, it is grooved, the grooves being denoted by g,' and'one of-the said grooves in connection with thefluglz. in the valve chamber 7 shownv in Figs.. 2 and 5y prevents the rotation of the valve and the exposure of either groove tothe opening leading to the drain pipe 12.

' A compressed spiral spring 19 on the valvestem 15, andconfined endwise between `the packing box 17 and a collar 20 ont-he stem, tends to keep the valve 14 on its seat 'aroundtheopening d; andt prevent leak age through the packing box, should the stem become reducedy insize by continued ,use,"or Athe packing be defective, the stem isprovided with a'rubber collar j which is within the spring-19, which when the valve 1s lifted, bears tightly against the bottom of the box and sealsit.y

22' is the seat fastened Vto the' branched lever A24 ywhich lis fulcrumedv p to. a 'lug 25 on the'topof the shell 2 The ends ofv the 4branchesfof the lever 24 are connected by means of1inks`27 to a ycrosshead., 29 hel'd'b;7

jam nuts to the stein 15. The object of thisy indirect connection between the lever 24 and the crosshead 29 is to prevent thelarc d escribed by the ends `of the' lever givinga lateral movement to the stem.

. 30 is a valve seat inthe shell2, and 32 a valve v l Its stem 33 extends `through a packing box 35 atthe top vof the shell` 2; and due to the valve being yieldingly supe ported in an open condition by means of.

the coiled spring 37 the stem bears against a 'lug 39 forming a part of the branched lever 24, and `thereby coperates with the spring 19 to hold theseat22 yieldingly in an elevated position.

Supposing the various partsv of the apf paratus to be in the positions shown in Fig. 2, it will ,be understood that th'e flushing tank is-empty, the opening d closed by the valve 14 and the drain' pipe 12 in communication with the main pipe 6 so that no water is trapped and-liable to freeze in the appa-A ratus. When the seat 22 is4 depressed, the valve 32 is closed, and Water under service pressure passes the valve 14 and enters the flushing tank 5 which is immediately filled. At the same time the drain pipe 12 is closed and in consequence there is no escape for t-he entering water. When the seat 22 vis allowed to rise, the valve 14 cuts off the sup ply water, and the valve 324 being opened, the bowl is flushed by lwater descending from the tank 5; and any water remaining in the shell 2 lelis'oiit through the drain which controls the opening within -the seat.

-trol the iushing passage, a stem' leading' from -the valve,-a seat-supporting lever .ful-

f specified.

crumed to the shell with one arm thereof bearing on the ushing valve stem, a valve l chamber situated below 4and in communication with the shell and through it with the .iushing tank, having a drain pipe and an opening leading to a source of supply of water under pressure, a sprin held and normally closed valve to contro the source of water supply and also the discharge through the drain pipe, and a stem leading from the second valve and connected with the other arm of the seat-lever, substantially as 2. In a non-freezing water closet, the combination of ,a' ,practlcally closed flushing tank, a bowl, a shell interposed between and open to the said parts, having a lushin passage therein, a spring-supported, an

normally unseated valve to control the iushing,y passage, a stem leading from the valve, a seatsupp'orting lever fulcrumed to the lslrell with one arm thereof bearing on the v sure, a non-rotate stem, a cylindricalvalve chamber situated below and in Comunication with the shell, having a drain pipe and an opening leading to a source of supply of waterl under presle spring-held and normally closed valve in the cylindrical chamber, to control the source of water supply, the same having. a` stem which connects it to the other arm of the seat-lever, and a cylindrical'and longitudinally grooved part to control the' drain pi e opening, and ada ted when lifted to a stantially as specified.

3. In a non-:freezing bination' of a practlcally closed 'flushing tank, a bowl, a shell interposed between and open to the saidparts having'a ushin passage. therein, a spring-supported an normally unseated valve to control the fiushing passage, a stem leading from the Valve, a

it water to the shel and thence tothe flushing tank, subseat-supporting lever fulcrumed to the shell v with one arm thereof bearing on the Stem, a c lindrical valve chamber situated below an in communication with the shell, and also with the flushing tank, having a drain pipe opening, and a radially projecting internal lug, a sprin -held and vnormally closed l valve situate .in the cylindrical chamber, to control the source of water supply, having a stem, a Kcrosshead on the stem,

and links which connect the'crosshead with the other arm of the lever, the said valve having a cylindrical part t'o `control the drain pipe opening and grooves either one o f which is adapted to receive the said lug,

and also adapte when the valve is lifted -to admit water to the shell and thence to the,

iushing tank, substantially as speciied.
